Seite v - Xftbograpbic plates, THE object of this book is to describe the modern practice of Bridge-Construction, and to set forth in the simplest language the mechanical principles and experimental facts on which it is based. The design and arrangement of the work have been dictated by a desire to render it as useful as possible, not only to Engineers or Draughtsmen who may be engaged in the work of Bridge-Calculations and Bridge-Construction, , but alsoto students.

Seite iii - A PRACTICAL TREATISE ON BRIDGE-CONSTRUCTION: Being a Text-Book on the Construction of Bridges in Iron and Steel. FOR THE USE OF STUDENTS, DRAUGHTSMEN, AND ENGINEERS. BY T. CLAXTON FIDLER, M. INST. CE, Prof, of Engineering, University College, Dundee "The new edition of Mr.
Seite 373 - In an ordinary spectronometer, if the grazing angle 6, is determined by the position of the reflected beam of X-rays these errors may be either positive or negative, according to the position of the axis of rotation of the crystal with reference to what we have called the effective reflecting plane. Further, they may increase or decrease with the wavelength of the rays, and in limiting cases the size of the crystal would have an effect on them. Our method of using the spectrometer eliminates these...
Seite 159 - R, the behaviour of the column will be different — the load itself will not produce any deflection, but the smallest conceivable force applied to the middle of the strut will be sufficient to bend it to any required extent...
Seite 404 - V is the velocity in miles per hour, and p is the corresponding pressure in pounds per square foot.

Seite viii - ... materials as they possess, and the most that can be done is to take the experimental facts that have been actually ascertained, and to study their real bearing upon the questions at issue. Throughout the work, I have of course consulted on all occasions the most recent experiments and deductions, and have endeavoured, to the best of my knowledge, to mention in their proper places the authors of recent discoveries or improvements, and to refer to scientific papers which have furnished sources...
